Answer:
If your looking for I the answer is -3
Step-by-step explanation:
Simplify both sides of the equation
1/2(4i+8)=-2 - Distribute
(1/2) (4i) + (1/2) (8) = -2
The subtract 4 from both sides
Then divide both sides by 2
Answer:
(2x)^3+(y)^3=(2x+y)(4x^2-2xy+y^2)
Step-by-step explanation:
a= 2x and b = y
then a^3 + b^3 = ?
We know that:
a^3+b^3 = (a + b)(a^2 – ab + b^2)
Putting a =2x and b=y and finding the answer
(2x)^3+(y)^3=(2x+y)((2x)^2-(2x)(y)+(y)^2)
(2x)^3+(y)^3=(2x+y)(4x^2-2xy+y^2)
So, (2x)^3+(y)^3=(2x+y)(4x^2-2xy+y^2)
